how to bulk update records in a table?

  • Hello, I have a silly question which I am looking for a quick solution:

    Say I have a table with 100000 records, there are col1 and col2

    I want to update col1 with col2 for each record, how to do that? I don't want to use cursor or any complicated way, there should be a fairly simple way to do this, right?

    Thanks.

  • update tablexxx

    set col1 = col2

  • Thanks Tom
